Subject: [PATCH 4.14 22/31] iommu/amd: Set DTE[IntTabLen] to represent 512 IRTEs
Date: Thu, 10 Dec 2020 15:26:59 +0100	[thread overview]
Message-ID: <20201210142603.204326253@linuxfoundation.org> (raw)
In-Reply-To: <20201210142602.099683598@linuxfoundation.org>

From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>

commit 4165bf015ba9454f45beaad621d16c516d5c5afe upstream.

According to the AMD IOMMU spec, the commit 73db2fc595f3
("iommu/amd: Increase interrupt remapping table limit to 512 entries")
also requires the interrupt table length (IntTabLen) to be set to 9
(power of 2) in the device table mapping entry (DTE).

Fixes: 73db2fc595f3 ("iommu/amd: Increase interrupt remapping table limit to 512 entries")
